| Feb 27, 2023 at 21:01 | comment | added | JBH | @Negdo You have a good point, but keep in mind that you're challenging the backstory, not the question. When a question is independent of the backstory (like this one), it's not appropriate to worry too much about the backstory. Think of it this way, "ignoring how I got there, can I...?" | |
| Feb 27, 2023 at 15:55 | comment | added | Yulian | @Negdo Yeah, the fussion powering the ship will probably one of those rare few moments when my world would have to deviate from the "100% realism" principle on which the entire setting is built | |

Even project Orion (en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)) was relative slow. Fusion or not (rocket equation is evil thing!). What you need is a stelaser: a star powered laser. Which we have theoretical knowledge how to build one, but not nearly the engineering knowhow (or required space infrastructure to even start). And we aren't just a few decades away from one. Unlike with net plus fusion, where we don't even know if it's even possible outside of stars/bombs. | |
| Feb 27, 2023 at 15:32 | comment | added | Yulian | It will be a generational ship travelling below the speed of light, though still at a significant % of the speed of light. My assumption is that fusion power will be of net plus energy output at that point and that the reactor present at the Ark will still be an early model. I did some estimates very long ago regarding the optimal time window for getting the most out of gravitational assists in the solar system and I think the launch would happen in the 60's-70's, I completely forgot the details though. | |
| Feb 27, 2023 at 15:07 | comment | added | Negdo | When would your ship sail from Earth? Because you mentioned no more than 4 decades into the future. While we have technology to travel to other star systems we don't have infrastructure (or even engineering knowhow) to do so. It is more or less impossible to successfully launch a starship with goal of reaching a target 1800 light years away in less than half a century. | |
